Merging many soundsets?

I’m asking for advice. I’d like to make a scene with moods from many others.
Let’s say i want a mega tavern soundset with all the moods from the various tavern soundsets. What i’m doing now is:
I create the mega tavern
Then i go on each of the moods and i copy it to mega tavern.

This works but has 2 issues:
It creates redundant copies of sfx if used in different moods
I have to manually add the sound buttons.

Is there a way to make it right clean and fast?
